Computer-Aided Design (CAD) is the design and construction of a product by means of EDP. In the beginning, CAD software was a tool for technical drawings, but today CAD systems (2D and 3D CAD programs) include many more functions and support the design. CAD systems are used in almost all areas of technology: e.g. architecture, civil engineering, mechanical engineering, toolmaking, electrical engineering and even dental technology. Computer-Aided Engineering (CAE) refers to all forms of computer support of work processes in design to improve product design or facilitate the solution of technical problems for many industries. Photorealistic renderings facilitate the visualization of concepts and ideas. Designs can be tested under real conditions using simulations.
